SUMMARY: The aim of the meeting is to put together real data: cosmological, astrophysical, particle, nuclear physics data,
and hard theory predictive approach connected to them in the framework of the LambdaWDM Standard Model of the Universe.
Recently, Warm (keV scale) Dark Matter emerged impressively as the leading Dark Matter candidate.
Astronomical evidence that Cold Dark Matter (CDM) and its proposed cures (CDM + baryons) do not work at galactic and
small scales is staggering. LambdaWDM solves naturally the problems of LambdaCDM and agrees with the observations at
galactic and small scales as well as large and cosmological scales. In the context of this new Dark Matter situation,
which implies novelties in the astrophysical, cosmological and keV particle physics context, this 17th Paris Colloquium 2013
is devoted to the LambdaWDM Standard Model of the Universe.

TOPICS: Observational and theoretical progress on the nature of
dark matter: keV scale warm dark matter. Cored density profiles in agreement with observations. Large, galactic and
small scale structure formation in agreement with observations.The new quantum mechanical framework to galactic structure:
WDM core sizes in agreement with observations. The clarifying and unifying WDM framework for stars, galaxies,
black holes and cosmology. Warm (keV scale) dark matter N-body simulations in agreement with observations at large
and intermediate scales. Neutrinos physics, astrophysics and cosmology. Neutrino masses, mixings, phases and oscillations.
Sterile neutrinos at the keV scale and at the eV scale.
Active and sterile neutrino mass bounds from cosmological data and from high precision beta decay experiments.
